Application filed January 17, 1921.

Z '0 oZZ to 7mm it may concern Be it known that I, SAMUEL I. Benn, a citizen of the United States of America, residing at Youngstown, in the county of Mahoning and State of Ohio,-have invented certain new and useful Improvements in Combination Armor and Inner Liners, of which the following is a specification.

My invention relates to improvements in inflatable tires of that class wherein an inuer tube is designed to be inflated by pumping air into the same; and the object that l have in view is to provide an improved means for preventing the inner air-tube from being penetrated or punctured by tacks, nails, or other sharp objects, but without appreciably detracting from the resiliency or elasticity of the tire.

In my invention I provide an armor as a protection for the inner tube and at the same time an inner liner reinforcing the casing, ordinarily incasing the inner tube. in order to do this I have provided an armored inner liner comprising a series of three differently formed overlapping plates arranged and combined in a novel manner to afford protection to the inner air chamber or space of the tire and allow the tire to have the expansion and freedom of movement necessary in tires for vehicles.

To enable others to understand my inven tion, I have illustrated the preferred embodiment thereof in the accompanying drawings, forming a part of this specification, and in which Figure 1 is a perspective section of a rim, an outer casing, my improved armored inner liner and inner tube.

Fig. 2 is a detail perspective view of one of the armor plates.

Fig. 3 is a detail perspective view of another form of armor plates used in the construction of my improved armored inner liner.

Fig. 1 is a detail perspective view of the third form of armor plates used in the construction of my improved armored inner liner.

Like numerals of reference denote corresponding parts in all the figures of the drawing, referring to which: 1 designates an ordinary rim for holding the casing 2. inside this casing 2 is the armored inner liner 3. Within this armored inner liner 3 is the innertube 4.

It will be seen by referring to Fig. 1 that I have left an outer edge 5 of the armored inner liner 3 which may be trimmed off when the armored inner liner 3 is properly installed.

In the construction of the armored inner liner 3, 1" have used fabric and rubber in constructing the inner liner part. This fabric and rubber part is made thickest at the tread and gradually diminishes in thickness as it reaches the edges 5.

In securing the armor plates to this portion of the armored inner liner 3 a row of plates 6 are first secured along a line marking the lower edge 7 of the armored portion of the device. The clenching members 8 are caused to penetrate the inner liner part and are clenched on the inner side of said inner liner part, the edge 9 extending downwardly. These plates are cut from soft galvanized steel or other suitable mate rial and are rectangular in form and curved to a similar arc of the curve on the inner side of the casing 2.

A second row crf plates 10 are now secured to the inner liner part 1. These plates 10 are rectangular in form and are formed with clencher members 11, and a centrally located upward and outward bend 12 parallel with the edge 13. By again referring to Fig. 1 it will be seen that the plate 10 overlaps the plate 6 down as far as the bend 12.

The next step is to place a plurality of rows of the plates 10 so that the edge 9 overlaps as far as the bond 12. Finally plates 10 meet at the center of the tread at point 1 1. It will be seen that there is now a portion of only one thickness at the top of the tread. in order to complete the gradual curve and make a double thickness, the plates 15 are now riveted to the plates 10 and the inner liner part of the armored in ner liner 3 by means of rivets 16 passing through the holes 1'? of the plates 15.. I

lit will be seen by referring to Fig. 1 that all the plates are curved in order to fit snugly along the inner side of the casing 2.

It will also be seen that the plates are laid so that they break joints similar to that of laying shingles. This is done in order to provide a strong resisting surface to penetration.

What I claim is 1. In a device of the class described, an inner liner, a row of curved rectangular soft steel plates secured to said inner liner at ap proximately the centers of the side walls 0i": same, a plurality of rows of rectangular soft steel plates, an upward and outward bend in said plates, secured to said inner liner so as to overlap, a row of rectangular soft steel plates secured by means of rivets to the center of the armor tread, substantially as described for the purpose set forth.

2. in a device of the class described, an inner liner, in combination with two lower rows of rectangular soft steel plates, a plurality of rows of rectangular soft steel plates, an upward and outward bend in said plates, overlapping of said plates, a central 15 row of rectangular plates secured to said inner liner, substantially as described.

In testimony whereof I afiix my signature.

SAMUEL I. BAER.
